The Treaty of Bucharest (1918) was a peace treaty between Romania on the one side and the Central Powers on the other, following the stalemate reached after the campaign of 1916–17 left Romania isolated after Russia's unilateral exit from World War I (see Treaty of Brest-Litovsk). Alexandru Marghiloman, then Prime Minister of Romania, signed the treaty at Buftea, near Bucharest, on 7 May 1918 and it was ratified by the Chamber of Deputies on 28 June and by the Senate on 4 July 1918. However, King Ferdinand refused to sign or promulgate it.

The treaty put Romania in a unique situation compared to other German-occupied countries. It completely respected Romania's de jure independence, as it did not impose any form of vassalage or protectorate over Romania, and even though the country had to cede land, it still emerged bigger than before entering the war, after the Union with Bessarabia.

Germany was able to repair the oil fields around Ploiești and by the end of the war had pumped a million tons of oil. They also requisitioned two million tons of grain from Romanian farmers. These materials were vital in keeping Germany in the war to the end of 1918.[6]

Although Bulgaria received a part of Northern Dobruja, it continued to lobby Germany and Austria-Hungary for the annexation of the whole province, including the condominium established by the Treaty of Bucharest. After negotiations, a protocol regarding the transfer of the jointly administered zone in Northern Dobruja to Bulgaria was signed in Berlin on 25 September 1918, by Germany, Austria-Hungary, the Ottoman Empire and Bulgaria. In return, Bulgaria agreed to cede the left bank of the Maritsa river to Turkey. However, this agreement was short-lived: four days later, on 29 September, Bulgaria capitulated in the face of the advancing Allied forces (see also the Armistice of Salonica).

The treaty was denounced in October 1918 by the Marghiloman government. Romania re-entered the war on 10 November 1918, the day before it ended in Western Europe, and the 1918 Treaty of Bucharest was nullified by the Armistice of 11 November 1918.[7] In 1919, Germany was forced in the Treaty of Versailles to renounce all the benefits provided by the 1918 Treaty of Bucharest.[8] The territorial transfers to Austria-Hungary and Bulgaria were annulled by the Treaty of Saint-Germain-en-Laye (1919), and the Treaty of Neuilly-sur-Seine (1919), respectively; and the Treaty of Trianon (1920) settled Romania's border with Hungary.
